PROCESS OF MANUFACTURING- ADMMOIIIUM GELOREZD.

Application filed August 28,

To all whom it may concern:

Be it known that 1, ANDREW GORDON FRENQH, a subject of His Majesty'the King of the United Kingdom of Great Britain and Ireland, resident of Villiamson avenue, Grey vincial District of Auckland and Colony of New Zealand, chemist, have invented an .lmprovement. in a Process of Manufacturing Ammonium Chlorid, of which the following is a specification.

- In carrying out my improved process for the manufacture of ammonium. chlorid from coke or carbonized coal Whichcontains sulfur and nitrogen I drench the dry and porous coked combustible with a strong brine of common or sea salt and Water, and introduce the material thus prepared into any convenient form of kiln, oven, or furnace and burn the same with an admission of atmospheric air and steam. A chemical reaction takes place at a low red heat between a portion of the oxygen of the air the sulfur and nitrogen of the carbonized coal and the steam resulting in the production of ammonium chlorid which being a volatile substance vaporizes and may be caught in any convenient flue chamber, or other form of condenser. Where sea water is conveniently obtainable it may with advantage take the place of a Specification of Letters Patent.

Fatented March 1'7, T2908 1905. Serial No. 275,18-59,

burnin mass to spray the sea Water over the uirerl repeatedly in order to'supply the quantity oi salt.

I find alter numerous trials and investigations that to obtain the completed. conversion of all the nitrogen present in the "aiming material each pound oi" nitrogen requires about one and. one seventh Jounds sulfur and about four and one hal pounds (.5 com: mon sea salt and these proportions being; given all the nitrogen is taken up and. con verted into ammonium chlorid.

A full and sharp blast of air expeditcs the burning and does not injure the anunonium chlorid so long as steam ispresent in not less than ten per cent. of the volume of the blast.

llaving'iully described my in'venti what '1 desire to claim and secure by Letters .iiatent A process or manufacturing ammonium chlorid which consists in drenching carbonized coal containing sulfur and nitrogen with a strong brme and then burning said drenched carbonized coal by suluecting' it to a current of air containing at least 10 per cent. ol steam.
